FIXING APPARATUS AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18360925 titled 'FIXING APPARATUS AND IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes a fixing apparatus that includes a rotatable fixing member, a rotatable pressurizing member, a heating portion, and a circuit portion. The circuit portion includes a contact member that is in contact with the fixing member and is configured to remove electric charge from the fixing member. The surface layer of the pressurizing member is electrically connected to the circuit portion via the surface layer of the fixing member. The surface resistivity of the pressurizing member's surface layer is represented by X (Ω/□), and the surface resistivity of the fixing member's surface layer is represented by Y (Ω/□). The following conditions are satisfied: 4.0 ≤ log X ≤ 13.0, 5.0 ≤ log Y ≤ 14.0, log Y ≤ 13.0 - log X, and log Y ≤ 23.0 - log X.

  • The fixing apparatus includes a rotatable fixing member and a rotatable pressurizing member.
  • The circuit portion of the apparatus includes a contact member that removes electric charge from the fixing member.
  • The surface layer of the pressurizing member is electrically connected to the circuit portion via the surface layer of the fixing member.
  • The surface resistivity of the pressurizing member's surface layer (X) and the fixing member's surface layer (Y) must satisfy specific conditions.

Potential applications of this technology:

  • Printing and copying machines
  • Industrial manufacturing processes requiring fixing or pressing operations

Problems solved by this technology:

  • Prevents electric charge buildup on the fixing member
  • Ensures efficient and reliable fixing of materials

Benefits of this technology:

  • Improved performance and reliability of fixing apparatus
  • Reduced risk of malfunctions or damage due to electric charge buildup


Original Abstract Submitted

A fixing apparatus includes a rotatable fixing member, a rotatable pressurizing member, a heating portion, and a circuit portion including a contact member and configured to remove electric charge from the fixing member, the contact member being in contact with the fixing member. A surface layer of the pressurizing member is electrically connected to the circuit portion via a surface layer of the fixing member. In a case where a surface resistivity of the surface layer of the pressurizing member is represented by X (Ω/□) and a surface resistivity of the surface layer of the fixing member is represented by Y (Ω/□), 4.0≤log X≤13.0, 5.0≤log Y≤14.0, log Y≥13.0−log X, and log Y≤23.0−log X are satisfied.
